It gets easier when you make the conscious decision to stop caring.
We can't control what our idiot spouses do. I realized that early on. My wife is an even bigger idiot than your husband. That's her problem, not mine, and not the kids' and nobody else's.
I do hope your husband comes to his senses. Some people actually like living that way, but people like us (and most others on this board) like a more stable and civilized life. Perhaps you should envision a life without all the drama. Would it be worse than what you're going through now?
